osteopenia of prematurity (oop) is a preventable disease. improved survival of premature newborns is associated with an increased incidence of oop. the purpose of this study was to compare the prophylactic effects of two low doses of vitamin d (200 and 400 iu/day) on the clinical, biochemical and radiological indices of the rickets of prematurity. in a randomized clinical trial, 60 preterm newb...

purpose: to study the effects of adding intravitreal bevacizumab (avastin) to conventional laser treatment on regression of retinal neovascularization in threshold rop. methods: intravitreal injection of bevacizumab (1.25 mg) in one eye of each of three newborns with threshold rop was performed in addition to laser treatment. the other eye of each patient was treated with laser alone. changes i...

The purpose of this article is to explore the psychosocial antecedents of prematurity. Emphasis is on conceptual areas and supporting literature for (a) the contexts in which prematurity occurs and the diversity of women's experiences; (b) a lifecourse approach to prematurity that highlights allostatic load and the accumulation of trauma and loss in possible prematurity pathways; and (c) divers...

OBJECTIVE To evaluate the prevalence of retinopathy of prematurity and the risk factors affecting very low birth weight infants at a neonatal intensive care unit. METHODS A cross-sectional study investigating all newborn infants with birth weights < or = 1,500 g and/or gestational ages < or = 32 weeks, admitted to the Neonatal ICU at the Hospital de Clínicas de Porto Alegre, from October 2002...

BACKGROUND Low birth weight (LBW) can result from prematurity or intrauterine growth restriction (IUGR) and result in small-for-gestational-age (SGA) infants. Prematurity and IUGR may have different etiologies and consequences. OBJECTIVE Our objective was to analyze seasonal patterns of prematurity and SGA in a rural African community and to compare them against variations in nutritional and ...

Background: Retinopathy of prematurity is a vascular retinal disease that can cause blindness in premature new born babies. Several risk factors are associated with the incidence of ROP. Information and data on risk factors associated with ROP in context to Nepalese population is scarcely documented in literature. Objectives: The purpose of this study was to evaluate the risk factors of retinop...

Treatment of ventricular arrhythmias (VAs) commonly involves ablating sites showing electrograms with the earliest activity relative to the VA, but there is no threshold value for prematurity guaranteeing success. Ablation of sites with great prematurity can still result in failure.We hypothesized that isochronal map area (ISCA), derived from isochrones indicating electrogram prematurity, could...

OBJECTIVE To describe retinal detachment with macular holes in infants with retinopathy of prematurity and the methods of surgical repair with their outcomes. METHODS A retrospective review of 4 cases of retinopathy of prematurity and 1 case of retinopathy in a full-term infant that resembled retinopathy of prematurity, in which a macular hole and associated retinal detachment developed and s...

background: recent studies have demonstrated the high prevalence of vitamin d deficiency in the general population. pregnancy and preterm delivery are known as risk factors for vitamin d deficiency. consequently, vitamin d level in women with preterm deliveries might vary from those with term pregnancies. in this study, we aimed to compare vitamin d level in term and preterm infant–mother pairs...

abstract background: preterm labor (delivery after 20 weeks and before 37 weeks of gestation) is the leading cause of prenatal mortality in developed countries. many women who have pre term labor have abnom1ally high plasma levels of a-fetoprotein in early pregnancy. methods: this study was designed to evaluate the ability of this biochemical test and a clinical risk factor scoring system to pr...
